AWS Certified Cloud Practitioner — Question 336

A cloud engineer needs to track AWS costs. The cloud engineer also needs to receive event driven alerts when costs exceed specific thresholds.

Which AWS tool provides this functionality?

Answer options

• A. AWS Cost Explorer
• B. AWS Budgets
• C. Cost allocation tags
• D. AWS Cost and Usage Reports

Correct answer: B

Explanation

AWS Budgets allows users to set custom budgets that track AWS costs and usage, triggering event-driven alerts via email or SNS when thresholds are breached. AWS Cost Explorer is used for visualizing and analyzing historical cost data but does not natively send event-driven alerts for threshold breaches. AWS Cost and Usage Reports provides detailed raw billing data, while cost allocation tags are used to categorize and track costs rather than alert on them.
